2022+ Honda Civic Si - Front Pipe Back Exhaust w/ Polished Tips

2022+ Honda Civic Si Front Pipe Back Exhaust — Polished Tips

The 11th-gen Civic Si (FE1/FE2) came back with a turbocharged 1.5L, a proper 6-speed manual, and a platform worth building for. Thermal R&D has been engineering exhaust systems for compact and subcompact platforms since the early 90s — so when the new Si launched, this was personal. The result is a front pipe back system tuned specifically for the Si's exhaust path, built to give it the aggressive, refined sound it deserves without drone, without compromise, and without cutting a single factory mounting point.

Key Features:

• Lifetime Warranty Backs Every System We Build
• 2.5" T304 Stainless Mandrel-Bent Tubing For Maximum Flow And A Drone-Free Aggressive Sound
• True Helmholtz Technology Cancels Drone At The Source — Not By Choking Flow
• Internal Helmholtz Chambers For Reduced Weight And A Cleaner Install
• High-End Compression Clamps For Maximum Adjustability
• Full Polished Tips — Direct Fit, No Gaps, No Adapters
• Direct Bolt-On Using Factory Mounting Points — No Cutting, No Welding

Built from T304 mandrel bent stainless steel with precision bends that keep exhaust velocity consistent from the front pipe all the way to the tips. The Helmholtz chambers are built internally — reducing weight and cost without giving anything up in sound quality. Straight-through exhaust flow with drone-cancelling characteristics built right into the design. Clean, aggressive tone under throttle. Composed and controlled on the highway.

The full polished tips fit flush with the factory bumper — no gaps, no adapters. Prefer a blacked-out finish? Also available with black coated tips.
